Also celebrating the milestone, mobile game developers have included Android characters and birthday cakes in their titles.
A year ago today, Google brought together all of its digital content under a new overarching Google Play brand, available both online and on Android devices.
Not only did the move give Google's digital store a new unified identity, but it also created an outlet through which Google could market and sell other products, such as the Nexus line of hardware.

Marking the one-year anniversary, Google has introduced a sale on Google Play.
Movies such as 21 Jump Street and The Smurfs have been discounted, along with books including Mark Sennen's Touch and I'm Watching You by Mary Burton.
EA games Plants vs Zombies and Need for Speed: Most Wanted are available for 99p and £1.50 respectively.
Several mobile games - including Clouds & Sheep, Royal Revolt, Yumby Smash and Disney's Gnome Village - have created special content for the Google Play first anniversary.
This mostly revolves around little Android in-game characters and lots of birthday cakes.
